Digital isolators are electrical components or circuits designed to transfer digital signals between two electrical domains while ensuring effective electrical isolation.
The ADUM4473CRIZ-RL is a BiCMOS digital isolator designed to provide electrical isolation between two digital signals with a maximum common mode transient immunity of 15kV/μs. It features a single 3.3V power supply, an operating temperature range of -40°C to +125°C, and a minimum modular insulation voltage of 3.75kV RMS. It provides a field-programmable delay from 0 to 400ns for I2C compliance, as well as a low quiescent current of 3μA (typical).
ADUM4473CRIZ-RL is a high-performance digital isolator, ideal for use in low-voltage power systems, automotive and industrial applications. It is a high-speed digital isolator with a data transfer rate up to 20 MHz and a propagation delay of 85ns. The digital isolator features a built-in ESD protection circuitry to withstand electrostatic discharge up to 10kV, with a noise filter for I2C lines helping to reduce common-mode noise.
The working principle of the ADUM4473CRIZ-RL digital isolator is based on its magnetic isolation technology, which uses a transformer to isolate the input and output channels from each other. The transformer works in synchronous mode, which drives an opposite current through the primary and secondary in response to input signal changes. This current is then converted to a voltage across the secondary side, which drives the output signal, thus providing effective electrical isolation.
In addition to its magnetic isolation technology, the digital isolator also has an onboard capacitance that amplifies the signal voltage before transmitting it across the isolation barrier. This amplifies the signal voltage and ensures that it stays within the designated voltage range on the other side. The digital isolator also features built-in protection circuitry that helps protect it from electrical overstress.
The ADUM4473CRIZ-RL digital isolator is an ideal choice for applications that require high data rates, absolute isolation, EMI/EMC protection, as well as low-power consumption. Its high-speed data transfer rate, wide operating temperature range, and ultra-low quiescent current make it an ideal choice for a wide range of power system, automotive and industrial applications. It can be used in combination with other digital isolators to provide an additional level of isolation and protection.
